This book will focus on Xen, LXC, and KVM, but other noteworthy
implementations include the following: .... The simplest model is the bridge model
; all the eth0 network cards (both in the dom0 and the domU systems) behave as
if they were directly plugged into an Ethernet switch. ... These three networking
nodes involve a number of interfaces with unusual names, such as vif* , veth* ,
peth* and xenbr0 .
